Bomb Attack Kills 9 On Pakistan Bus

Suspected militants bombed a bus carrying prisoners in northwest Pakistan on Thursday, killing at least nine people as fighting between security forces and extremists flared across the country's tribal belt.

The powerful blast left a massive crater in the middle of a bridge in Bannu and left the burnt-out vehicle completely mangled.

The fresh violence came just over a week after longtime U.S. ally Pervez Musharraf resigned as president, triggering a scramble for power that collapsed Pakistan's governing coalition.

The party long led by slain former Prime Minister Benazir Bhutto is now in a position to dominate the government and it is toughening its stance against Islamist extremists.

The Pakistani Taliban, meanwhile, are becoming increasingly bold, claiming responsibility for a wave of suicide bombings and gun attacks.

No one immediately claimed responsibility for the attack Thursday, though police said militants were the likely culprit. It happened as a bus carrying prisoners crossed a bridge in Bannu, a town in the North West Frontier Province, said Waqas Ahmad, an area police chief.

The dead included police officers and prisoners, said Jalil Khan, another police official. But he could not provide an exact breakdown.

Hours earlier, security forces drove off a Taliban attack on a fort and pounded another band of militants holed up in a health center, officials said Wednesday as fighting spread to new areas in the tribal belt along the Afghan border.

But the initiatives have borne little fruit, and U.S. officials have been pressing for tougher action against insurgent groups blamed for rising violence across the border in Afghanistan and in cities further inland.
